Limits to Interstellar C4 and C5 towards Ζ Ophiuchi
We have made a sensitive search for the origin bands in the known electronic transitions of the linear carbon chains C4 and C5 at 3789 and 5109 Å towards ζ Oph (AV ≤1). The incentive was a recent detection of C3 in this interstellar cloud with a column density of 1.6×10 cm plus the availability of laboratory gas phase spectra of C4 and C5. Further, some models of diffuse interstellar clouds pre...
متن کاملMolecular emission from the diffuse gas around ζ Ophiuchi
Wehavemappedλ18cmOH andλ9cmCH emission from the diffuse gas around ζ Oph, and find no trace of emission from the +4.5 km s−1 gas whose OH line was previously believed to represent pre-shock gas. The pattern of OH emission is strikingly dissimilar to those of CO, HCO+ and CH in that the strong +1 km s−1 component seen to the South is largely absent in OH. CH more closely resembles CO, peaking on...
متن کاملAn ab initio study of the electronic structure of the boron oxide neutral (BO), cationic (BO⁺), and anionic (BO⁻) species.
The BO neutral, cationic, and anionic molecular species have been painstakingly studied through multireference configuration interaction and single reference coupled cluster methods employing basis sets of quintuple cardinality. Potential energy curves have been constructed for 38 (BO), 37 (BO(+)), and 12 (BO(-)) states and the usual molecular parameters have been extracted most of which are in...

Downloaded by guest on 12 Febru fistula or sinus or recurrence or persistence of infection. Surgical management included incision and drainage alone, incision—drainage and curettage or SCJ resection. The type of the surgical management depended on various factors including the initial presentation of the patient, the patient’s general condition, radiological findings and recurrence after initia...
متن کاملGenetics: C. Stern
which involved various strains of race A and race B coming from diverse parts of the distribution area of each race. These races were of different "strength," and had different types of Y-chromosomes (Dobzhansky and Boche,6 Dobzhansky7). The details of chromosome morphology and chromosome differences between the two races of Drosophila pseudoobscura is now in press elsewhere., The present ident...
